Description

[Detailed description of the invention] (Field of industrial application) This invention is a bolt connection embedding device that is buried in the concrete ceiling surface in advance in order to vertically attach ceiling suspension bolts, etc. to the concrete ceiling surface. It is related to.

(Prior art and its problems) Traditionally, this type of embedding device involves inserting and fixing the embedding device main body, which is provided with a screw hole for screwing a bolt, into the center hole of the mounting pedestal. It is generally known that nails are inserted on both sides of the periphery, but since the bottom surface of this mounting pedestal is a horizontal surface, the bolts are slanted against the sloped concrete ceiling surface of the top floor. It cannot be used to be installed.

In order to eliminate this, for example,
As disclosed in Publication No. 92106, an implant has been developed in which the lower surface of the mounting pedestal into which the implant main body is inserted is formed into an inclined surface having a certain angle. Even if it can be applied to a roof with the same slope as the surface, it cannot be used on a roof with a different slope, and as a matter of course, it cannot be used at all on a horizontal concrete ceiling surface.

(Purpose of the invention) The present invention was made in view of the above problems, and can be used whether the concrete ceiling surface is horizontal or sloped. To provide a bolt connection embedding device which can be used according to the slope by preparing several types applicable to the slope.

(Structure of the invention) In order to achieve the above object, the bolt connection embedding device of the present invention has an embedding device main body having a screw hole that opens downward, which is inserted into the center of the mounting member, and the mounting member A plurality of nails are inserted and fixed to the outer periphery of the embedding device, and a vertical hole having a diameter larger than the screw hole of the implant main body is provided in the center, and a nail insertion hole is provided in the outer periphery to allow the nails to pass through. A pedestal member having an inclined lower surface is removably attached to the lower surface of the mounting member, and the screw hole faces downward through a vertical hole in the pedestal member, so that it can be attached to a horizontal concrete surface. When installing in
When the installation is performed on a ceiling surface having a slope, a pedestal member having a slope that matches the slope is attached to the lower surface of the mounting member.

(Explanation of Embodiments) The embodiments of the present invention will be explained with reference to the drawings.
is a metal implant main body having a circular cross section with a large-diameter circular head 1a at the upper end, and its shaft portion 1b is inserted and fixed into the central hole 3 of a mounting member 2 made of reinforced synthetic resin, and further, A screw hole 4 is provided at an appropriate length above the lower surface of this shaft portion 1b. Also, mounting member 2
The lower surface of is formed in a horizontal plane perpendicular to the central hole 3.

Numerals 5 and 5 are nails whose upper portions are inserted into and fixed to the small-diameter cylindrical portions 2c integrally provided on both outer peripheries of the mounting member 2, and whose lower portions from the center portion protrude vertically downward. The head 5a at the upper end is connected to the small diameter cylindrical part 2.
The upper end of the projection 5b protruding from the head 5a is brought into contact with the lower surface of the head 1a of the implant main body 1.

The mounting member 2 has a mounting plate portion 2a whose lower surface is a horizontal surface at the lower end, and this mounting plate portion 2a
A large-diameter cylindrical portion 2b into which the shaft portion 1b of the implant main body 1 is inserted into the center and both sides of the upper surface, and a small-diameter cylindrical portion 2 for nail insertion.
c, but the whole may be formed into a block shape.

A cylindrical body 6 is integrally hung at the center of the lower surface of the mounting member so that the central hole 3 extends vertically downward, and has an inner circumferential surface slightly larger in diameter than the screw hole 4.

A pedestal member 7 is made of the same material as the mounting member 5, and has a vertical hole 8 in the center of the upper surface of the lower end seat plate 7a through which the cylindrical body 6 can be freely inserted and removed.
b is provided, and the nails 5 are provided on both sides of the cylindrical piece portion 7b.
It is formed by integrally providing a small-diameter cylindrical portion 7c having an insertion hole 9 through which the
The lower surface of a is formed into an inclined surface 10 corresponding to the slope of the concrete ceiling surface of the roof to be constructed. or,
A horizontal joint plate part 7d having the same shape as the mounting plate part 2a is integrally provided at the upper end of this pedestal member.

Note that from the upper surface of this joint plate portion 7d to the seat plate portion 7a,
The vertical hole 8 and the insertion hole 9 are in communication with each other over the lower surface. It is also convenient to prepare several types of inclined surfaces 10 on the lower surface of the seat plate portion 7a depending on the slope of the ceiling surface.

When the bolt connection embedding device configured in this way is to be buried in the concrete surface of a roof having a slope, a pedestal member 7 having an inclined surface 10 corresponding to the slope is used, and the vertical hole of the pedestal member 7 is used. 8 and the insertion hole 9, respectively, and insert the cylindrical body 6 and the nail 5 of the mounting member 2, and stack the mounting member 2 on the upper surface of the pedestal member 7.
In this state, as shown in Fig. 2, nails 5, 5 are driven into the formwork 11 through the insulation material 12 laid on the formwork 11 having an inclination, so that the screw holes 4 are directed vertically downward. , pour concrete 13.

In addition, when buried in a horizontal concrete surface,
As shown in FIG. 4, it is sufficient to set the screw hole 4 in the vertical position using only the mounting member 2 from which the pedestal member 7 has been removed.

FIG. 5 shows another embodiment of the present invention, in which an implant main body 1 is inserted into and fixed to the central cylindrical part 2b of a mounting member 2, through which the upper ends of nails 5 are inserted and fixed on both sides. In this case, the shaft part 1b is inserted into the vertical hole 8 of the base member 7 without providing the cylinder 6 on the lower surface of the mounting member 2. It is inserted removably.

The other configurations are the same as those of the previous embodiment.

(Effect of the invention) As described above, according to the bolt connection embedding device of the present invention, in addition to the mounting member 2 having the embedding device main body 1, the pedestal member 7 whose lower surface is inclined is attached to the lower surface side of the mounting member 2. Since it is attached removably, when the concrete ceiling surface is horizontal, the mounting member 2 can be buried in the concrete without using the pedestal member 7, and the screw hole 4 for bolt connection can be arranged vertically. If the concrete ceiling surface is sloped, it is possible to prepare several types of pedestal members with sloped surfaces according to the degree of slope, so that they can be easily and accurately attached to the mounting member 2 according to the slope. It can be buried with the screw hole 4 for bolt connection facing vertically downward, and the pedestal member 7 can be easily attached and detached from the mounting member 2, improving work efficiency.
